The purpose of this paper is to develop a conceptual analysis of hydrogen production from biomass research in literature by quantifying the main bibliometric performance indicators, identifying the main authors, countries, journals and research areas and evaluating the intellectual structure and evolution of the field using SciMAT as a bibliometric analysis software. In this way, the methodology implemented in this research encompasses both the bibliometric performance analysis and science mapping approaches of biomass-based hydrogen production research themes. The bibliometric performance analysis is centered on the citation-based impact of the scientific output, while science mapping illustrates the evolution of the research themes that build the field through the use of bibliometric network analysis techniques. The publications related to biomass-based hydrogen production research available at Scopus have been compiled between 1979 and 2019 (876 publications). Finally, the paper provides objective evidence of the evolution of the hydrogen production from biomass field, which confirms the interest that researchers have in this theme to develop new capabilities. Finally, it offers a framework to support researchers evaluating the field and, finally, to assist them in the development and direction of their future analysis identifying trends in terms of research
